My wife and I are bi and have always been very open about sharing partners and experiences. We believe what works and makes both of us happy is the best approach to life. When she was offered a job in south Florida, we decided to move there without much hesitation, as the job was in her field of interest and an exciting opportunity even if the pay was not great at first. Plus our swinging lifestyle fit in well with that of Ft. Lauderdale.
After a few months on the job, her work was going well and her client list quickly building, but no hint yet of a raise in pay to match her success.
She told me she really liked her boss, who was only a few years older than us and quite attractive. She said they got along well together and she thought that he was attracted to her also. I suggested she explore the possibilities and she said she would. Kevin, her boss, was in his mid forties, athletic and in terrific shape, divorced with a teenage son and daughter. His son played tennis in school and was on his college team. His daughter Kathy, spent most of her time in the briefest of swimming suits that left little to the imagination, which suited my wife just fine.
The next week after we had talked about what she could do to inspire a raise, she was in his office late in the afternoon going over a new account she had just acquired. She had taken off her bra to better stir Johns attention ( she has beautiful small firm breasts) and was wearing a fairly revealing blouse; all to not much effect. She said as they were finishing their planning session, the door to the office opened and his son, David, and his playing partner came in, celebrating their latest match win. They all had a beer to cool off and sat down while David described the match. She realized her nipples were quite hard and much on display for the boys, who had started to notice them. As she watched them, she could tell from their growing erections that their minds were drifting away from tennis and on to other things. She was sitting to the side of them and didn't know how far to take matters, but decided to have a little fun with them. With their eyes fixed on her tits, she casually opened her legs enough that they had a good view of her panties which were clearly wet. She saw Davids penis get hard enough to peek out of his tennis shorts. And when she demurely looked away, turned to John, who she caught rubbing his cock while he stared. Deciding it probably wasn't the best idea to let this go on much longer, she made her excuses, and left the office.
After she told me the story that night, I asked her if John could see her legs spread open; and when she thought about it, she said "no, he was looking at the boys. And when I asked her if he could see Davids cock, it was like a light went off in her head and she said, "Oh, shit". I told her maybe she needed to change her approach and ask John if he wanted to come over to our house after work for a swim. She said she would.
I had of course met John a few times and I felt that mutual tension that guys have who might be interested. Being bi, I certainly was.
The next day she invited him over for drinks and dinner on the following Friday and he readily accepted. I dropped her off at work Friday morning; she had asked him to give her a ride home that afternoon. That day she wore one of her casual Friday dresses that was basically see thru when she stood with the sun shining on her, and no panties to limit the view. When she got in his car, she sat so her dress rode up on her legs and he had a good look at her pussy. They flirted with each other, telling jokes, and she had occasion to bend over laughing and touch his leg as he drove. She told me later she was glad to feel his cock getting hard under her hand.
When they got to our house, I was in my shorts and tee shirt out by the pool. We greeted each other and I went to get beers for everyone. Paula said she wanted to get comfortable and for us boys to get to know each other. I suggested to John that we go outside by the pool while she changed. After we had been talking a few minutes, Paula returned in her light shower robe that she had only loosely tied, and she said. " I want to relax in the shower and lay down awhile in bed, maybe even take a short nap. Why don't you two enjoy yourselves and come in and wake me up when you're ready" Then she went in the kitchen to get us some more beer, and returning, let her robe come open so we both got a great look at her body, She left, and I noticed John looking at my growing cock, as we talked. In short time, I said lets jump in for a swim. John asked if he could borrow a suit, and I stood up and said, "no need here" and took off my tee and shorts. When John wondered about the neighbors, I told him we had a very nice relationship with them. He took off his shirt and began undoing his pants, which were hanging up slightly on his growing cock. So I laughed and reached over to help him, gently holding his cock to the side for him as he pulled his pants off. I commented on the fact he was commando under his pants and he just laughed and said it was Friday.
We jumped in the water and swam around, played a little grab ass with each other and finally challenged each other to a race. He won (actually, I let him), and pulled himself out of the pool, sitting on the side. I swam up to him and asked him what he wanted for a prize. He told me to stay in the water and suck his cock, which was now mostly hard and about 8 inches. This is what I had been waiting for and quickly put my mouth over the head and started to work up and down with my lips. It was still wet from the pool and as I continued, it began to get wet with his precum, which I licked off like candy. After a bit, he pulled me up out of the water, had me stand in front of him , and proceeded to use his mouth on my cock. He moved down to my balls, and as he sucked them, I felt his finger move to my ass, working slowly in my hole, I had started to moan from the sensation, when he got up and grabbed me, flipping me over on the pool deck and placing me on all fours. He told me he was going to do what he had wanted to do since we first met. Getting behind me he placed his cock against my ass and began pushing it in, at first slowly, then harder and faster. Now fucking me in steady, full on thrusts deep into my ass. He started talking about fucking my ass for me until I was a good boy, asking me how I liked having my ass fucked by dad and just as he was coming, he yelled out "I filling your ass with my cum, David, take it all, son" When he finished, he pulled slowly out and told me to hold his cum in because we were going to wake up Paula and let her taste your ass.
